Boating and Cold Water Safety

We want visitors to our recreation areas to have a fun and safe time.

We ask that visitors please observe and follow all boating regulations: Washington State Recreation and Conservation Office Boating Information Portal

  • Wear your life jacket: All vessels must have one readily accessible life jacket for each person on board.
  • Never boat or swim under the influence.
  • Travel at safe speeds.
  • Look for water level changes, floating debris, rock outcrops, and stumps. (Get lake level info at MyTPU.org/LakeLevels.)

It’s important to remember that warm air temperatures don’t equal warm water temperatures. Even if it’s hot outside, the water is extremely cold. The farther from shore, the colder the water can be as well.

According to NOAA, cold water drains body heat up to 4 times faster than cold air. Cold shock can be just as severe and dangerous from water temperatures of 50-60F as it is from water at 35F. Even experienced swimmers can quickly lose muscle control.
